Pulling data from a database is very simple and it's not much harder to add or change data in the database. We've only introduced you to some of the basics of SQL, and more will be covered in the book as we move along. SQL offers a tremendous amount of flexibility, which you'll need to know as you continue to learn more about web and database development. There are plenty of good SQL books on the market, and if you plan on working with databases, you should pick up a copy to learn more.
